Derailleurs at Halfords

Keep your derailleurs on top of their game by giving them regular TLC. They love being looked after and cared for, so give them what they want.

The front derailleur works by shifting the chain from one chain ring to another, while the rear derailleur shifts the chain up and down the gears on the cassette - so they're both rather important to enjoy a smooth ride.

Get yourself some good quality SRAM derailleurs and with regular care you can be sure they'll go the extra mile for you.

We also have a wide range of Shimano derailleurs to choose from so feel free to have a browse online or pop into you local store. We also fit for a small charge if you need a helping hand.
